Left on all night water on floor none in tank

If NO water or shampoo is coming out , then tank may be clogged . Check the On / Off valve that it opens and the filters are clean and in the correct location. If that fails then tank is clogged from shampoo being left inside the tank.

Hi, you could try the following steps, if you have not done so already. Some of these steps may seem like common sense, but it's for people to forget about checking the least expensive part to replace first, so if some of the steps are those that you have already tried, then feel free just to skip through to the ones you have not tried already.

1. 1
   Make sure the power cord is plugged firmly into the outlet. The steam mop will not start if it the power cord is loose.
   
2. 2
   Check the fuse box or circuit breaker connected to the outlet the steam mop is plugged in to. Replace any blown fuses. Reset any tripped breakers.
   
3. 3
   Check the water tank if the Shark steam mop will not produce steam. Add water to the tank if it is empty. The mop will not make steam without water in the tank. To fill the tank, turn the tank cap counterclockwise and lift it up to remove it. Set the filling funnel into the tank opening. Pour water through the funnel into the tank until the water level reaches the "Max" fill line on the tank. Replace the cap.
   
4. 4
   Inspect the microfiber cleaning pad if the steam mop is leaving water on the floor. If the microfiber pad is too wet, it will leave water on the floor. Unplug the mop from the wall outlet. Replace the microfiber cleaning pad. To replace the pad, move the latch strips out of the hooks on the mop head. Pull the pad off. Set the new cleaning pad on the mop head. Hook the latch strips onto the hooks on the mop head.
   
5. 5
   Use distilled water if the steam mop is leaving white spots on the floor. Hard water may cause white spots to be left.
   

If none of the above work, then is it something that you purchased recently, and is new? If you did, then it could still be fixed under the manufacturer's warranty regardless of whether or not the original length of the warranty has expired. This could be due to the fact that you have received a product that has some sort of manufacturing fault, rather than it stop working through misuse by the user.
If it's a common problem, then you will more then likely be able to return it to the manufacturer and have it replaced for a new one, let alone repaired :-) - This only applies to whether or not the item is New though :-).
Hope this info helps

this is by design. not all the water from the clean water tank will end up in the dirty tank, some is left on the floor, some evaporates.

Suggest that you do the following.
Remove the TOP ("Clean water") tank. Fill it 1/2 full of water. Put the top on the clean water tank and place it back on the machine.

Release the machine handle and remove the cover of the "dirty" water tank. Inspect the back of the tank to be sure that the vacuum adapter in located in the rear of the dirty water tank. If not-that is your problem. If yes, restore the top to the dirty water tank.

Power the machine on.
On a kitchen floor, power the machine on. Pull the trigger and hold it for about 30 seconds. You should see water gathering around the brushes. If not, that is a problem.

With water around the brushes, release and lower the handle and and move the machine over the water. It should vacuum the water into the dirty water tank.
Is all of that happening?

Does it put down clean water onto the floor? If so, rinse the four ports on the underside of the tank really thoroughly. You might have a clog; it's not difficult to dislodge it if you use enough warm water. Also make sure that the squeegees on the cleaning head cartridge (which holds the brush) are straight and in good condition.

If it doesn't put down water at all, try the tank rinse anyway, as it can help with that issue, too.

your suction tube where the water gets sucked up is clogged

Try one thing... the filter cover must be clicked into place. I thought it just sat on top, but it has to be pushed into place.

FWIW

There is a little post in the back where you insert the top solution/water tank, if you put the tank in incorrectly, (i.e., shoved it in, instead of putting it in at an angle, bottom first) there is a chance you broke it or bent it backwards. My mother broke mine, i've got the post but don't know the part, without that post inserted into the tank the water will not come out.

There are only a few things that can cause the condition you describe. First would be to verify that the vacuum/blower motor is running. You can test this by placing your hand on the floor opposite the side where the charger is connected and see if you feel air movement. If no air is felt, there's your problem. Second, there is a valve located in the dirty tank that if blocked will prevent water pick-up. To resolve and clear this condition will require several processes to occur at once. Fill the dirty tank half way with hot water, add Scooba cup of vinegar. Close the stopper and shake the "Good Grief" out of the tank. This action is necessary and may have to be repeated several times to clear the flapper valve in the dirty tank. Third, there may be a poor seal between the tank and the Scooba base. Verify that both the left and right sides of the tank are close to the base and equal in distance. If the right side is farther away from the tank (larger gap) then water pick up will be poor. Some Scoobe owners resort to using duct tape to hold down the tank. Fourth, verify that the thin rubber pieces on the bottom of the tank are not deformed and properly seated in the grooves. hope this helps
